ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electrical connector, and more particularly to an electrical connector with passive clips which provide accurate and reliable operation.
DESCRIPTION OF THE PRIOR ART
In order to ensure a reliable coupling between first and second connectors, latching means is arranged between the mated connectors. For example, the latching means generally includes locking loops arranged on opposite ends of the first connector, and looks on the second connector corresponding to the locking loops.
In general, the latching means can be divided into an active type, and a passive type. The active means that lock and/or unlock of the latching means require manual operation to trigger it. The passive means that lock and/or unlock of the latching means can be readily triggered without manual operation. Generally, connectors with smaller dimension is equipped with the passive type locking mechanism because the locking means is too small to be accessed. For example, the power connector used to charge the mobile phone has a comparatively smaller dimension and is equipped with the passive type locking mechanism. However, with such a small housing, arrangement of such passive type locking mechanism is really a problem.
In the existing art, the passive type locking mechanism is made from plastic material which experiences a material fatigue or insufficient retaining force.
SUMMARY OF THE INVENTION
An objective of this invention is to provide an electrical connector which a passive locking device which is integrally formed with a metal shield.
In order to achieve the objective set forth, an electrical connector in accordance with the present invention comprises a housing defining a receiving cavity which defines at least a rear wall thereof. A plurality of passageways extends through the rear wall. The housing has a top outer surface in which at least an opening is defined thereof and is in communication with the cavity. A tongue extends from the rear wall and defines a plurality of slots aligned with the passageways. An elongate strip is bridged between longitudinal ends of the opening and includes a biasing dimple extending into the cavity for engaging with the inserted connector.
These and additional objects, features, and advantages of the present invention will become apparent after reading the following detailed description of the embodiment of the invention taken in conjunction with the appended drawings.
